Abstract: Provided are marine fuels or fuel blending compositions, methods of making such fuels or compositions and methods of potentially reducing the life cycle carbon intensity of marine fuels or a fuel blending compositions. The marine fuel or fuel blending composition disclosed herein includes at least 20 vol % of a resid-containing fraction, and from 5 vol % to 80 vol % of one or more renewable fuel blending components. The one or more renewable fuel blending components includes one or more fatty acid alkyl esters. Optionally the one or more renewable fuel blending components may include gas-to-liquid hydrocarbons from renewable synthesis gas, hydrotreated natural fat or oil, hydrotreated waste cooking oil, hydrotreated tall oil, pyrolysis gas oil, or combinations thereof. Optionally, the resulting marine fuel or fuel blending composition can have a BMCI−TE difference value of 15 or less.

Abstract: Hydroprocessed residual fuel and/or fuel blending components are provided that have a sulfur and nitrogen level comparable to liquefied natural gas (LNG). Because of the low starting level of sulfur and/or nitrogen, the severity of the hydroprocessing that is needed for the crude oil or bottoms fraction in order to remove sulfur to a level that is comparable to LNG is reduced or minimized. This can allow the resulting marine residual fuels to have low carbon intensity, low SOx and NOx emission and high energy density. Since the hydroprocessed fractions correspond to a fuel oil product, the resulting marine fuel can be used in existing fleets, and can be distributed in existing bunkering systems.
